Convertable toy car having a two-level cam

Abstract

A toy car having a two-level cam, sound assembly, projection assembly, signal light, and a signal light activation arm. The two-level cam includes an upper and a lower cam and is driven indirectly by a battery-powered electric motor and a series of gears. The upper cam drives the projection assembly to project toy figures out of the car doors and springs cause the toy figures to return to their original position. The lower cam urges a spring-loaded signal light activation arm to urge a signal light to be intermittently rotated into position. Another cam indirectly drives a reverberation arm to move and also causes two lights to move. The sound assembly includes a sound-generation device, reverberation hole, and sound emission hole, with the sound-generation device being driven directly by the motor.

I claim: 
     
       1. In a toy car or the like with a chassis, outer body (9), electric motor means and transmission assembly (1) having an outer casing (12) mounted on the chassis (0), the improvement comprising: (a) a two-level cam (2) consisting of an upper cam (21) and a lower cam (22) being driven by a series of gears (128); said series of gears (128) being driven by a first worm gear (127) which is coaxial with a gear (126); said gear (126) being driven by a second worm gear (125); said second worm gear (125) being driven by a first axle (123) of the transmission assembly (1); said transmission assembly (1) being driven by said electric motor means;   (b) a signal light activation arm (8) which alternately driven rearwardly by the lower cam (22) of said two-level cam (2) and retracted by a spring (501), said spring (501) being attached to said chassis (0); said signal light activation arm (8) having a bracket (83) thereon;   (c) a signal light (7) which is pivotally fixed on a rear portion of the chassis (0) and which has a protrusion (72) thereon which is urgeable by said bracket (83) so as to clockwise rotate said signal light (7) into a signal light "on" position;   (d) a sound assembly (4) being mounted on said outer casing (12) of said transmission assembly (1); said sound assembly (4) including a reverberation hole (42), and a sound-emission hole (43);   (e) a projection assembly (3) which is fixed on top of said sound assembly (4); said projection assembly (3) including a left arm (31), a right arm (32), and a motion transfer gear (33); said motion transfer gear (33) being rotatably fixed between said left and right arms (31 and 32) and said left arm (31) and right arm (32) having respective teeth (311 and 321) on mutually facing sides thereof engaged with said motion transfer gear (33) so that said right arm (32) moves inwardly when said left arm (31) moves inwardly and said right arm (32) moves outwardly when said left arm (31) moves outwardly; said left arm (31) being alternately driven outwardly with respect to said chassis by said upper cam (21) and retracted by a spring (312) and said right arm (32) being alternately driven outwardly by said motion transfer gear (33) and retracted by a spring (322); a muffle (101) being attached to said left arm (31) and covering said sound-emission hole (43) at its original position, said muffle (101) synchronously moving in the same direction to reveal or recover said sound-emission hole (43) as said left arm (31) moves outwardly or inwardly;   (f) a reverberation arm (6) having a pad (62) on one side thereof; said pad (62) abutting against said erverberation hole (42) of said sound assembly (4) at its original position, a first end of said reverberation arm (6) being fixed to another spring (63) mounted on said outer casing (12) for returning said pad (62) back to beat against said reverberation hole (42) in order to generate an alarm sound effect; and   (g) a second cam (5) which is fixed to a second axle (124) of said transmission assembly (1); said second cam (5) intermittently driving a lever arm (61) which is pivotally attached to said outer casing (12) of said transmission assembly (1); said lever arm (61) having a first end which is driveable by said second cam (5) and a second end attached to a second end of said reverberation arm (6) for driving said reverberation arm (6) to reciprocate when said second cam (5) intermittently drives lever arm (61).
